This is what I'm doing and it's working fine. I have the K3 set up for 13mS of keying pre-delay. That is, the K3 keys the amp 13mS before the K3 produces RF. A shorter delay may work, but I'm being conservative because I don't want to fry vacuum relays. :) Study the addenda to the K3 documentation to find the menu setting. 73, Jim K9YC _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
